Tiny Sound Waves Help Protect Quantum Computers

Topic: Research News

Scientists at Harvard have found a way to use sound waves to protect sensitive quantum computers. They used tiny packets of vibration called phonons to keep the computers' memory safe from noise. This breakthrough could help build smaller, more powerful quantum networks.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have made a significant discovery in the field of quantum computing. They found a way to use tiny sound waves, or phonons, to protect delicate quantum information from noise.

The team, led by Eliza Cornell and Zhujing Xu, used a structure called a phononic cavity to trap mechanical vibrations. These vibrations interact with the electron spin inside a qubit, making it possible to move quantum information between different parts of a network. However, protecting this memory is a major challenge in quantum computing.

The researchers addressed this problem by demonstrating what they call
